    The 'virtual particles' are photons. As far as I understand, it is one of several equivalent ways of describing an electromagnetic interaction. There is the familiar inverse-squared electromagnetic force, but the next term in the series has an r^6 in the denominator, so it matters on a much shorter distance.

    The idea that the so-called Casimir force could be made small or negative with a geometry change has been around for a long time. The outcome for a particular geometry is not easy to theoretically predict though.

    The summary is bad. For the most part its not about reduction in surface area. So all the comments about how obvious it is that the force should go down with surface area are ignorant.

    Almost everything one reads about the Casimir force is based on a misunderstanding of the math tricks used to derive it for parallel plates. Its the van der Waals force, with nothing meaningful going on with 'infinite vacuum energy'. Some scientists are to blame for the confusion, because they exploit the misunderstanding to get funding from ignorant DoE and DoD program managers.

    So the summary is misleading, as always, and many of the slashdot comments are off base, as always. The study itself may or may not be stupid or spun in a dishonest manner, I'd have to read the paper and get up to date on other research in the last ten years in order to know. Based on past experience, I would not be surprised either way.

    Also....For a non-flat surface, the force can't be estimated from surface area and distance, it doesn't work like that. The resonances are different depending on the shape. A good estimate of the force of attraction (or repulsion) would have to be derived from first principles, which would be prohibitively difficult for all but the most trivial of geometries. Its not right to say that the reduced force is due to the reduced surface area.

    I think the essential thing to understand is that people have different abilities and needs. No category is quite adequate. I have trouble with speech, but unlike your son, apparently, I have almost no "mind's eye" at all, and a terrible memory for anything that I can't logically relate to other facts or feel in a musical way. I don't think that necessarily means that he's more or less genuinely Asperger's than I am. One of my three children has trouble with speech also, and is overly affectionate with strangers by most people's standards. He is very different from me in a lot of equally significant ways. Some people have characterized my social skills as Asperger's like, but I think the main difference is I have less of a veneer of pretense over everything. I actually don't think I'm lacking in social skills or social perceptiveness at all, relatively speaking. I think that slick, salesman types have just been more successful at getting their particular strengths and characteristics defined as the norm. (Though the 'sociopath' category is a win for my team I suppose.) One of my other children has freakishly good language and social skills: he was able to BS comfortably with adults as if he were a peer when he was 2. I don't think this is a syndrome either though, just something he's really good at, and strengths almost always come with other weaknesses and tradeoffs. He's smart, but his 'Asperger's-like brother is smarter in some ways, and that intelligence has a deep connection to his speech difficulty, in my opinion. He finds it harder to put things into words in part because he's able to think in ways that don't map neatly into a string of grammatical concepts. People are complicated machines, and in everyone a lot of small pieces are broken or don't work well, and other interrelated pieces that may be genius. It just may or may not be recognized depending on how externally obvious those pieces are.

    That analogy seems to imply that people who waffle new-agey platitudes are somehow experts. I can't say they're wrong, but I wouldn't defer to their judgement anyway. When people talk about "higher realities" and "deeper truths" and the like, they're forcing the assumption that these unmeasurable subjective experiences are more fundamental to the universe than the laws of physics, and anyone is within their rights to call bullshit on that.

    People who waffle new-agey platitudes may or may not understand much of anything, and I wouldn't defer to their judgment in any case.

    But if you want to know what you're talking about when calling bullshit, you need an adequate understanding of the ostensibly "unmeasurable subjective experiences" in question. How unmeasurable and subjective are they really? Are they in agreement with the remarkably successful model commonly thought of as "laws of physics", or do they contradict it, or do they fall outside of that scope? You're guessing that your knowledge is adequate to make a reasonably informed judgment that the new-agey claims are all bullshit. My assertion, based on my experience with a subject I've devoted much of my life to studying, is that your knowledge is not adequate.

    You're right that the new-agey claims are mostly bullshit. But there's stuff that's true and that can be understood to matter mixed in with the bullshit. If you don't want to hassle with trying to separate the two, and just want to ignore all of it, that's a reasonable stance in my view. Not everyone has time for this stuff. But then if you make strong assertions about other people's beliefs and experiences, very often you'll just be wrong.

    Many scientific subjects require a lot of effort to understand to more than a superficial degree also. The physics of physics journalism, for instance, or even undergraduate physics, is typically a sketchy caricature of real physics. Most of what seems "counter-intuitive" to people about 20th century physics seems that way because its described in a way that's actually wrong. Understanding dreaming doesn't require the same type of kind of logical rigor as physics, and the abstractions are different, but takes a lot of work to sort out what's real from what's not.

    When I first had astral projection experiences in the mid 90's, I messed around with it, figured out what I was doing with my senses, and dismissed it as meaningless. It took me ten years to discover that there was more going on than the more superficial aspects of the experience, even though I was mostly right about the part that I thought I understood. And if I'd put less effort into it, or my luck had been a bit different, I never would have figured that out. I'm not claiming intellectual superiority, I'm just sharing what I can see from where I am now, that if you put a fair degree of effort into understanding dreaming, you find that there's a lot there that's not what it seemed at the outset. I'm not even expecting you to take my word for it: I don't think that putting that kind of faith in other people's claims is a good idea. But I think if you relax your judgment a little bit, leaving the door open a little wider to the possibility that people like myself are not just blowing smoke, then you'll be 'forcing assumptions' a bit less yourself.

    Certainly an expert in the field would be able to convey why it is a worthwhile endeavor. Can anyone offer me a shred of evidence that there is signal in the noise of dreams?

    I can do that if you tell me what sort of information you would regard as evidence, provided of course that you haven't decided the outcome already.

    I don't claim though that there is signal in the noise of your dreams, or that dream recall is worthwhile for you personally. Some people dream vividly for much of their time asleep, and its an important part of their problem solving process. Other people do more of the same kind of thinking while awake, or they don't do much of it at all. Personally I don't have much of a "mind's eye" while awake: my visual imagination is dominated by processing sensory information, and my intuition is remarkably restricted by my conscious thought process. I dream vividly every night though, and get insights that don't come as easily while awake.

    If you're skeptical primarily on the grounds that my experience is different than yours, and on the belief that your experience is a more reliable measure of my activities than my experience is, then I'm not going to convince you.

    Similarly, I probably won't be able to convince you if you are one of those people who insist that peer reviewed studies are the only valid evidence, as if everything under the sun has already been studied to conclusion. Or as if it was impossible to use objective evidence to inform one's understanding before there were panels of credentialed experts for everything.

    But if you're as free-thinking as your sig seems to imply, then I think it shouldn't be a problem.

    Because dreams provide an insight into your superconsciousness

    How has this assertion been demonstrated empirically?

    It is difficult to demonstrate empirically because there are many uncontrolled variables. And the methodologies that have been developed for other applications such as clinical trials aren't ideally suited here. By way of analogy, progress in physics in the 19th and 20th centuries required development of statistical tools to deal with measurement uncertainty. Here there's uncertainty also, but its of a different type, where the parameters of the study itself are difficult to control. It is possible to get real, objective information, but difficult to do it in a way that will attract funding, will be easy for other researchers to reproduce, and will be understood by people who are quick to misapply assumptions gained in other fields.

    Because you can Lucid Dream.

    And what's the benefit of that?

    There are a wide variety of motives for lucid dreaming, but its often possible to become aware of things about yourself and the way your mind works that are difficult or impossible to discover in a normal waking state. You can have more conscious access to processes that are typically subconscious for instance. I agree that this is not of interest or benefit for everyone, but it is for some people.

    Because you explore higher realities and learn about yourself.

    What reason is there to believe that "higher realities" exist? What reason is there to believe that dreams help you "learn about yourself" any more than reading tea leaves?

    Much of what a person can experience while lucid dreaming is difficult to interpret and understand, and people tend to describe things to themselves in a way that may not be very accurate or objective. For example, many people believe they interact with some kind of exotic 'astral matter', but I've had those same experiences and I'm not convinced that idea is valid. One reads a lot of bullshit on these topics, both from enthusiasts and skeptics. Its a very poorly understood subject area, maybe comparable to the study of electromagnetics in the middle ages. Sorting out the reality from the bullshit will take a lot of time and effort.

    I think you're a smart guy Hatta, one of the best /. contributors. But I think you're a bit out of your element here, like someone who has merely used a computer forming strong opinions about kernel development. It would take many hours of discussion with someone who studies dreaming as a serious hobby before you even understand what the major issues are and how words are being used. I'm not suggesting that you didn't ask good questions, just that you're not going to get good answers to them unless you have a fair amount of time and interest to explore those questions and consider the responses with a critical but open mind.

    Responding as if you're serious....This supposes that the soul is made out of some kind of exotic matter that exists where your body is and nowhere else. I think it is not localized like that, but exists everywhere, and influences and is influenced by your body as determined by the characteristics of your body. I also seems likely to me that mortality and immortality are ideas that only make sense when applied to bodies, not to souls. It would be immortal if it possessed a state that exists independent of bodies. It would be mortal if it possessed a state dependent on a particular body or population of bodies.

So people suppress their emotions, or logic, or deny some part of the picture that makes the remaining part more palatable. But different people see different things clearly, and fudge their worldviews in different ways.

Or maybe they could understand, but they can't stand the despair of seeing that there's very little that can be done. Conspiracy theories tend to represent the world in a simplistic, toy-like manner, where problems really could be fixed if only the right approach were taken.

    I think the first dynamic you mentioned, where their skewed view causes them to interpret information in a way that reinforces their skewed view, is an important part of this. But actually all systems of thought are like that, even though they're just not all quite as ridiculously brittle about it. For example, a scientifically inclined skeptic tends to view everything that can't be rigorously measured as unreal. So they ignore everything that can't be rigorously measured, since it unreal, so life continues to look that way.

    Years ago I listened to Art Bell and had all kinds of paranoid thoughts about things. Then I quit my alienating job, and got in a situation that was healthier for me, and the conspiracy thinking immediately stopped. It wasn't because I become less egotistical.
